摘要:
The invention is a static dimensional material which comprises multiple submaterials interwoven or joined according to their lengths of characteristics such that, when one material is stretched to its elastic deformation limit, another will begin its elastic deformation regime. Ropes or cords made from the invention are useful in the securing of loads at a far greater strength-to-weight ratio than conventional materials that are currently used to secure loads. Furthermore, the tactile feedback inherent in the invention will alert the user that the load is secure or that the tie-down is losing its static quality and should be replaced, in either case long before the end user is exposed to hazard.

A coating method for gypsum board comprising forming a gypsum board entrained with polymer additive in a surface layer, applying a preferably acrylic primary coating, curling and drying, and passing the gypsum board through a first roll coater wherein a second fluid coating is deposited over the primary layer, which forms a chemical bond with the entrained polymer, and a chemical bond with the second fluid coating. A coating material which can form copolymer bonds with the second coating is then deposited on the same, then dried and cured, resulting in coated gypsum board having a low surface tension surface, essentially impermeable to water, vapor or moisture penetration. In another aspect, at least one polymer additive entrained in a surface layer of the gypsum board and capable of forming a copolymer bond with a second coating is applied either on-line or off-line from the gypsum board formation line.

Sintered elements for use in hazardous areas comprise a first flame path having a first length and a first pore size, and a second flame path having a second length and a second pore size. The second length is greater than the first length and the second pore size is greater than the first pore size. Sounders and loud speakers for use in hazardous areas comprise a housing having a horn and a rear enclosure, a driver assembly, and a sintered element.

Plaque munie d'au moins un bord recourbé et procédé de fabrication d'une telle plaque. Le procédé de fabrication selon l'invention de plaques munies d'au moins un bord recourbé, à partir d'un extrudat (11) qui est extrudé à chaud entre deux feuilles (7,8), l'ensemble étant ensuite calandre, est notamment remarquable en ce qu'on utilise deux feuilles (7,8) de largeurs différentes et que la matière est extrudée de manière à recouvrir sensiblement toute la surface de la feuille (7) plus large en débordant de la feuille (8) plus étroite sur au moins un côté constituant ainsi au moins un bord (17a, 17b) longitudinal formé par la feuille (7) plus large recouverte seulement de l'extrudat (11), ledit bord se recourbant alors sans autre intervention par contrainte mécanique naturelle au cours de la fabrication, de manière concave du côté de la feuille (7) moins large. L'invention concerne aussi en tant que telle une plaque formée d'un noyau en matière thermoplastique pris en sandwich entre deux feuilles (7,8) dont l'une (8) est moins large, constituant au moins un bord (17a, 17b) longitudinal formé par la feuille (7) plus large recouverte seulement de la matière thermoplastique (11), ledit bord (17a, 17b) étant recourbé de manière concave du côté de la feuille (8) moins large.
摘要:
A foundation system includes metal framing members that support a reinforced, lightweight, dimensionally stable cementitious panel. The foundation system is non-combustible, water durable, mold and rot resistant, and termite resistant. The panels employ one or more layers of a continuous phase resulting from the curing of an aqueous mixture of inorganic binder, for example, calcium sulfate alpha hemihydrate, hydraulic cement, an active pozzolan and lime. The continuous phase is reinforced with glass fibers and contains lightweight filler particles, for example, ceramic microspheres.

A laminate-clad molding (10) includes an elongated molding body (14) having a base (16) and a surfacing body (18) substantially parallel to and connected to the base (16) via a stem(22) in a manner defining a first recess (24) along a first side of the stem, the first recess (24) being shaped and dimensioned for receiving an edge (28) of a first plank(12) in a manner permitting planar movement of the first plank (12) relative to the molding (10). A strip of decorative laminate (20) is secured to the surfacing body (18) to form a surfacing structure (56). A method for manufacturing the laminate-clad molding (10) is also disclosed.

A light-diffusing film includes a particle layer containing a polymer matrix having dispersed therein an effective amount of light-diffusing particles, and having a thickness in the range of 5mil to 20mil. The film may optionally also include a second polymeric layer adjacent and substantially coextensive with the particle layer, the second layer being translucent and having a thickness in the range of 5mil to 50mil. A third translucent layer may also be added. Molded articles having the inventive films on their surface, and methods of making them, are also disclosed.
摘要:
An improved gypsum slurry that includes water, calcium sulfate hemihydrate, a polycarboxylate dispersant and a modifier. The modifier is chemically configured to improve the efficacy of the polycarboxylate dispersant. Preferred modifiers include cement, lime, slaked lime, soda ash, carbonates, silicates and phosphates.
